Comment (by kencu):

 Getting stuff to use the additional symbols in legacysupport takes a
 variable amount of work.

 One way that might be needed here is to relink the binary against the
 libSystem.dylib from LegacySupport that re-exports the additional symbols
 that legacysupport provides, in addition to all the standard stuff in the
 system's libsystem.

 All this has been done already, of course -- but things change, new
 versions of stuff comes out, blah blah, and things need to be looked at
 again to see that they still work right.
